Abstract

We describe a search for ψ(3770) decay to two-body non-DD̄ final states in e+e- data produced by the CESR collider and analyzed with the CLEO-c detector. Vector-pseudoscalar production ρ0π0, ρ+π-, ωπ0, π0, ρη, ωη, η, ρη′, ωη′, η′, K*0K0̄, and K*+K- is studied along with that of b1π (b10π0 and b1+π-) and π+π-π0. The largest amount of disagreement between the expected rate for e+e-→γ*→X and that for e+e-→X at s=3.773GeV is found for X=η, at an excess cross section of (2.4±0.6)pb [Γηψ(3770)=(7.4±1.6)keV], and a suggestive suppression is seen for π+π-π0 and ρπ. We conclude with form factor determinations for ωπ0, ρη, and ρη′.
